 There are various ways to analyze the application. In some situations it is possible to
 compare two implementations and use System.currentTimeMillis() to find out which one is faster.
 But this does not work for complex applications with many modules, and for memory problems.

 A very good tool to measure both the memory and the CPU is the
 <a href="http://www.yourkit.com">YourKit Java Profiler</a>. This tool is also used
 to optimize the performance and memory footprint of this database engine.

+A simple way to profile an application is to use the built-in profiling tool of java. Example:
+</p>
+<pre>

+<h2>Database Profiling</h2>
+<p>
+The ConvertTraceFile tool generates SQL statement statistics at the end of the SQL script file.
+The format used is similar to the profiling data generated when using java -Xrunhprof. 
+As an example, execute the the following script using the H2 Console:
+</p>
+<pre>
+SET TRACE_LEVEL_FILE 3;
+DROP TABLE IF EXISTS TEST;
+CREATE TABLE TEST(ID INT PRIMARY KEY, NAME VARCHAR(255));
+@LOOP 1000 INSERT INTO TEST VALUES(?, ?);
+SET TRACE_LEVEL_FILE 0;
+</pre>
+<p>
+Now convert the .trace.db file using the ConvertTraceFile tool:
+</p>
+<pre>
+java -cp h2.jar org.h2.tools.ConvertTraceFile 
+  -traceFile "~/test.trace.db" -script "~/test.sql"
+</pre>
+<p>
+The generated file <code>test.sql</code> will contain the SQL statements as well as the
+following profiling data (results vary):
+</p>
+<pre>
+-----------------------------------------
+-- SQL Statement Statistics
+-- time: total time in milliseconds (accumulated)
+-- count: how many times the statement ran
